COMBINED TYrEwn-,iriiyre Ann COMPUTING MACHINE.

ToaZZ lwhom t'may concern.' i

` s Beit known that l, Bunnies; L. ferien `Narr a citizenoi' the United States, residing in Elizabeth, in the countyoi1 Union and State ot New Jersey, have Invented certain This invention relates to combined typewriting and computing r aehines and is herein applied to a machine oi the Underwood-Hanson type, in which the numbers to be computed set up on index pins by the numeral keys and are subsequently run into diahwheels .by mechanism Yactuated by an electric or other rmotor substantially Vas shown in Patent No. idll, issued to Frederick A. Hart August 2l, i917. Th tabulating mechanislA includes a series o" keys, at the depression of which the motor is started anda carriage stop is raised and latched in eiiectiye'position until struck by a column stop on the carriage.

, A feature oi my invention consists in inaking kit possible `to control the tabulating .movements ofthe carriage by the general operatorQ Ar-:cording to one form of my invyen'tion aslierein illustrated, when a 'tabulating key is depressed, lalter a number is written and indexed, to position the carriage :ior a succeeding computation, the motor will be started tovrun the indexed number into the number'wheels, but the typewriter carriage willV be held until the end oi the computing action; then ithe carriage will be released bythe/computing mechanis' ,to complete tile tahulating By this mode ouoperation, the'operatiye is'enabled to manipulate the typewriter in the ordinary manner, paying-no attention tothe computing' mechanism or 'to the tabulating mechanism, and needenly make sure to employ a tabulating keyto position the carriage i'or computation.

Aiiiother feature is that the tebulaaing key may be inetfectiye to start the motor heiore a number is set up on the pins so that the carriage may be tabulated into the tiret com- Y kpiring lZone without idly actuating the com# puting mechanism. Y

another feature is that the computing vmechanism may be automatically put undercontrol'oi the tabulating keys by the type- Speeieation of Letters atent.

`Application filed May 2, 1918. Serial No. 232,06.

writer carriage after a number is set up on the index pins.

Another rfeature is that the typewriter carriage may automatically disconnect the cemputing mechanism Jfrom the control ei' the tabulating keys when said carriage moves ou'toi' a computing zone so that ordi- Y nary tabulating may be performed thereafter .without idly actuating the computing mechanism. y

Another feature provides means whereby the operative may predetermine whether the actuation oi the tabulating keys shall start only a tabulating operation, or the computing mechanism also, at predetermined positions the carriage.

Other features and advantages will hereinafter appear. l

Numeral keys 10 and character keys 1l mounted on key levers l2 (Fig. l)V actuate wardly and rearwardly against' a platen l5 Y mounted on a typewriter carriage i6. To

letter-eed the carriage, heels 17 on the type- Y bars actuate a universal bar 18 to swing dogs i9 of an escapementV mechanism 20 provided with a` pinion 21 in mesh with rack 22 swingably mounted on the carriage.

A Series of tabulating keys 26 mounted on key levers 27 raise denominational stops 28 into the path ot' column-stops 29 adjustable on the carriage 1G, the stops 2S being adapted, through the intermediary or' connections to be hereinafter described, to raise the rack bar 22 of the typewriter carriage out of mesh with the pinion 21 of the escapement mechanism, permitting a spring drum 3() (Fig. 1) to draw the carriage in letter-feeding direction.

To compute the numbers typed upon the work-sheet on the platen, each numeral key lever 12 is provided with a pendant 34 (Fig. 1) which, on the down-stroke of the key, actuates a linkage mechanism oin an indexing device (Figs. 1 and 4), to depress a corresponding index pin 3G on denomina.- tional members 3T, having` racks 3S formed at their forward ends in mesh with pinions 8f) mounted on number wheels 4U. The denominational member 37, upon which a pin 3G is to be depressed, is moved into coperative relation with the linkage mechanism y) by a denominational selecting mechanism 41 (F igs. 1 and 4) controlled by the typewriter carriage in a manner common in machines of the Underwood-Hanson type.

lVhen a number is thus set up or registered on the pins 36, a power driven general operator 42 (Figs. 1, 4, 5 and v7) having a bar 43 universal. to all the denominational members 3T and moving in the path of the depressed pins 3G, is reciprocated to engage the pins and move iorwardly said denominational members amounts directly proportional to the digital value of the depressed pins to actuate the number wheels in accord with the value of the set pins.

A normally silent electrically driven motor 44 (Fig. 5), provided with a switch and connected with a reciprocating mechanism 46 (Figs. and 7), is provided for the purpose of driving' said general operator 42.

lVhen the general operator 42 reaches the end of its return stroke, the index pins 36 are returned to their normal positions by a universal plate 50 (Fig. 1) connected with a parallel motion device 51. Said plate is actuated by an arm 52 last on a rock shaft 53, (Figs. l, 5 and 7) which has at one end a downwardly-extending arm 54 engageable by a oneray pawl 55 mounted on the general operator 42, in such a manner that when said general operator is moved forwardly, said pawl will pass the arm 54 idly, but will actuate said arm on the return stroke of the general operator to raise the universal plate 50 and therewith all the depressed index pins 36, after which said plate will return to its normal position.

)Vhen the last digit of a number is typed and set up in the indexing device, the motor for driving the general operator. to run the number into the number wheels, may be started by a special key, not shown herein,

or the general operator* may be driven by a manually-operable handle 59 (Figs. 1 and 4) connected with gearing 60 to drive the general operator, after which a tabulating key 26 may be actuated to denominationally position the carriage 16 for typing the next number to be computed.

It is a great saving of time, however, to start the motor to actuate the computing mechanism and to tabulate the typewriter carriage at a single stroke of a key. For this purpose, the tabulating keys are provided with connections whereby the motor may be started and the carriage tabulated at a single stroke of any tabulating key. It is, however, undesirable to actuate the computing mechanism and the typewriter carriage concomitantly since the actuation of the typewriter carriage may actuate the denominational selecting mechanism 41 of the computing mechanism, while the parts of the computing mechanism are in action, thereby causing a malaction or wreckage of the machine.

To avoid this difliculty, means are provided whereby the carriage will not move until after the general operator 42 has run the first number set up on the pins into the number wheels 40.

For thus actuating the machine, the raised denominational stop i8 actuates a universal bar 64 (Figs. 1, 5, and 7) fast on a rock shaft 65 which has an arm 66 thereon, overlying an interponent 67 placed between the tabulating mechanism and the motor-starting mechanism, to depress said interponent 67 when positioned as shown in Fig. 5, and through the intermediary of a parallel motion device 68, depress the forward end of a bar 69 to swing a transverse lever 7 0 against the tension of its spring 71 to raise the latch 72 of the motor switch 45, thereby closing the circuit through the motor.

The rotation of the motor actuates the general opera-tor 42 through the driving connections 46, so that the universal bar 43 thereof engages all of the depressed pins 36 to drive the denominational members 37, to run numbers into the number wheels.

W' ith the parts positioned as in Fig. 5, the carriage will not be released at the depression of the tabulating key 26, since the rack bar 22 of the carriage remains in mesh with the pinion 21 of the escapement mechanism 20, thereby holding said carriage against tabulating movements.

lVhen the general operator 42 reaches the end oi" its return stroke` it actuates mechanism to disconnect the carriage 16 from the escapement mechanism 20, to permit the carriage to be rapidly drawn by the spring drum 30 until a column-stop 29 thereon strikes against the raised denominational stop 28.

For this purpose, the rock shaft 53 of the pin-restoring-device, Voperated by the general goperator {12,{is provided withL an upstanding arm 75 (Figs. 1, 4, 5 and7), tast thereon and connected'by al link 76 to a bellcraiik'77, to depress, by means of a pin-andslotconnection 77, an upwardly-extending -link78 connected tothe rear end otra lever 79. f- When said-link 78v is depressed at the end of the general operator stroke, the forkWard end of said lever 79 is raised so that a an extension 81 on the column-stop 29 moves to the apex of aca-m 82, formed at one end otra lever S3, 'iilcriimed tothe framework of the machine midway its ends, toraise a link 811attheotherendthereoyto swing e double bell-crank 85 to connect said up- LVi'vaidly-eizte ndiiig link 8 with the lever 7 9, said linkhaving a hook 86 iformed at its upper end,vvhich moves into engagement with Y ,a pin 87 at the rear end oi said lever 79, thus connecting said lever 7 9 with the computing Vmechanism..`A link 88 (Figs. 1, 5 and connectssaiddoublebell-crank 85 with the i' link 7 8,1-anda spring 89 serves to hold the Vce link 7 8 normally in the highest position peimitteolby its piii-and-slot connection 77"L with Vbell-ciaiik 77. 4

Y ySince Vthe carriage is held against a tabulating movement until the end of a computing-actioiriit isy desirable to hold the raised vdenomifiational stop 28 in eili'ective position during the actuation of the general operator anddiiringlthe actiiatioii of the carriage ina'tabulating operation. .Each denominational stop 28 is `provided with a latch .98

(Figs. 1, ,-2 and 5) to snapover a top plate 94;ofV the denominational stop housing when a stop 28 is raised; and is urged into latching "position by aleaf spring 95 (Figs. 1 and provided` foiiyeacli denominational stop.

Yllhen saidistopisrthus hitched, Vthe operative When a columnstop 29 strikes against the raised denominational stop Q8, the upper lend thereof Will be'moved leitivardly as iii Fig. 2, against its spring 95, to move the latch y93 'ont of engagement With said top plate r,94, and to permit-a spring 96. one toi1 cachot said .stops 28, to return said stop to its normal position. 'lt `will be noted that apertures 97 (Figs. 2 and' 3)'. are provided Ain theftop plate 9-1, throughivhich said stops 28 project, and each of said apertures is .of

with the lever 79,

siii'icient Width to permit the leftvvard movement of saidV stops While being raised or being unlatched.

To hold the carriage rack 22 out oi engagement with the escapement mechanism 20 during a tabiilating riin oit ythe carriage 16, the lever 79 which raises said rack is locked in effective position when actuated as in Fig". 5, by a latch 100 (Figs. 2, 3, 5 and 7), pivoted on the framework at L101 and urged into effective position by a spring 102.

`Wheii the carriage 16 reaches the end of atabulating run, it is restored to the control of the type keys when the stop 29 moves the upper end ot the raised stop .28 leftwardly and therewith-a slide 103 (Figs. 1, 2, 3 and 5), universalto all oi said stops 2S against the 'tension of a spring 104, so that a cani 105 formed thereon swings said lever-.locking latch 100 to ineilective position, to release the lever 79 and permit the carriage n ,rack-22 to mesh with the escapement mechanism 20.

To avoid idle actuation oi the general operator when a tabiilating key is depressed prior to a computation, as ivlien tabulating the carriage into the i'st computing zone. the mechanism for tripping the latch 72. which controls the motor 114-, is disconnected from the control of the tabiilating mechaiiism.

For this p uipose, the downwardly-extending' arm of the double bell crank S5 is connected by a link 109 (Figs. 1, 5 and 7) to the .ntei'ponei L 67 which lies between the tabiiating mechanism and motor-starting defices, to move the upper end. of said `interponent which underlies the arm 6G, forming part ci the universal bar 6s for thedenoininational stops, so that the upper endotsaid iiiteiponent will lie under a notch 110 in said arm in Stich a manner thatwliei said arm is actuated at the depression of a tabiilating rey 26, it will! be ineffective to depress the interponent'and start the motor. The downwardly-extending arm of the double bellcrank` 85 is also connected to link 67 by means of a spring' 199 Wliicn acts to restore link 67, bell-crank 85 and the parts associated therewith, to normal position.

in order to. release the carriage directly troni 'tlie-tabulating keys when the computing mechanism is noty controllable thereon, the arm G6 oi the universal bai' 64. associated with the denominational stops7 is connected to depressa link 111 (Figs. 5 and 7), the upper feiidof which is connected with the lever 79 for raising the i-ackQQ to disconnect the carriage Jifioin the escapement mechanism at the depression of tabulating key, said lever-79 being locked in 'effective position iii the saine manner asivlien the caiiiage is released by the Vgeneral operator. Said link 111 is connected to bell-crank 85 by means of a link'112 and by shifting said izo bell-crank either link 67 or link 111 Will` be effective to rock lever 79. The lever 79 is returned to its normal position when the carriage reaches the end of its run.

lVlien the typewriter carriage moves at high speed in a tabulatingaction, its column-stop 29 striking against a denominational stop 28 may cause a rebound oi thc carriage, thereby arresting,- 'the carriage at an incorrect denominational position, in case its rack 22 is engaged Withthe escapcment mechanism when said carriage is rebounded.

To avoid this difliculty, the typewriter carriage is provided with a speed governor 111 (Fie: which is pivoted on the machine ame at 11F and has a pinion 116 normally out e ment'ivith the rack lllhen the rack l is disengaged from the esoapen'ient niet' 2O in a tabulat- 'ing operation, by leve.' 9, an arm fast on said lever en` es an arm 117 fast on the speed governor 11 to swing the latter about its pivot 115 to engage its pinion 116 ivith the rack 22, so that the speed governor will be efl'ective to retard the carri ge, thereby reducing the force with Which its columnstop 29 strikes the raised denominational .stop 28, thus avoiding a rebound oi the typewriter carri-aon. The speed governor 114i will be held cil-lectiva position duriiw the run ell the carriage by the latch 100, tl ugh the intermediary oi' the lever i9 its computing mechanism, may be positioned so as to be effective for any desired letter-space position, and may be made of such extent as to be effective for a plurality of letter-space positions.

It will also be noted that the same columnstops 29 may be employed when it is not desired that the typewriter carriage shall render the tabulating keys efi'ective to control on the computing; mechanism. For this purpose, the extensions 81 of the column-stops extend only over a portion of their width so that a stop may be placed on the carriage with the extension 81 in or out oi engaging relation With the cam 82, as seen in Fig. 7, at the will of the operative.

lWhen it is desired to Write a Word or acharacter after a number to be computed, the carriage having been moved out of the computing Zone by this operation, the tabulating keys are inef'fective to control the computing mechanism. To avoidreturning` the carriage into the computing zone, in order to start the computing mechanismfrom said keys, the handle 59 may be actuated to run the indexed number into the number Wheels 4:0, and a tabulating key 26 may then be depressed in the usual manner to position the carriage for the next computation. The.

handle 59 may also be employed when it is desired to compute a number Written in a computing zone for which no properly positioned column-stop has been provided, Without the disarrangement of the column-stops 29, or in case a properly positioned columnstop 29 has been carried past cam 82 Without actuation of a tabulating lever to cause motor actuation of the general operator.

lVhen a tabulating key is depressed to start the computing mechanism, and to latch into effective position the associated denominational stop 28, the bar 69 (Fig. 7) will be held in depressed position until the denominational stop 28 is released by the typewriter carriage. It will be seen that if this bar 69 should hold the switch latch 72 in raised position until the end of the tabulating operation, the motor 44 will continue to drive the machine after the end of a computation.

To avoid this difficulty, the bar 69 is provided ivith a hinge 118, and is so proportioned relatively to the lever 70, that when said bar is actuated at the depression of a tabulating key 26, the forward end of the bar will trip off the end of the lever 70, a i'ter starting,r the motor 44, and the latch 72 and the lever 70 will immediately be returned to their Vnormal positions by the spring' 71. IN hen the lever 70 is thus returned, it Will swing the forward end of the bar on its hinge 118 against the tension ci a spring 119, provided to return said forivard end toits normal position above the lever 70 when the denominational stop 28 is released.

Variations may be resorted to Within the scope of the invention, and portions of the improvements may be used without others.
